let out a joyful shriek and sailed into her orgasm. With her brother she always had such fabulous climaxes, so intense they almost made her toes curl. She bounced around on the bed like she'd gone mad, but her brother had a firm grip on both cheeks of her ass, and he went right on pounding it to her until he brought her off three times. Then he sent his hot load gushing into her.
After they lay there for some time, catching their breath, Laura said quietly, 'Are you going to untie me now?'
'No way!' said her brother, grinning at her. 'I'm not finished with you yet.'
'W-what are you going to do?' she asked, feeling a little nervous again.
'You'll see,' he said, still grinning at her. With that, he went into the bathroom and when he came back a moment later, he had a wet hand towel in his hand. It was folded over so that it was a little over a foot long and about three inches wide.
'What are you going to do with that?' she asked, with a note of apprehension in her voice. That seemed to excite her brother even more.
'You know what I'm going to do, Sis, don't you?' said her brother. 'Sure you do.'
'No, I-I don't. Tell me.'
'Don't you remember what you said yesterday? You said you deserved a good spanking. I don't know what it was all about, but that's what you said.'
She remembered now. She had been thinking about the book she had done all that research on, about all the spying she had done on those women in Tuttleville. Then without telling her brother what she had been thinking, she said right out loud she deserved a good spanking.
'And you're going to…?'
He nodded his head and grinned.
'No! Forget it! I didn't mean it, honest. It was just a figure of speech. No, Ron. No!'
'If you promise not to yell too much, I won't put a gag in your mouth,' he told her. 'If you start getting noisy though, I'll have to stuff your panties into your mouth, so the neighbors won't hear you and wonder what the hell is going on in here.'
'No, no gag. Please.'
'Okay then. We'll try it without a gag. Get into position, Sis. Face down, with your ass in the air.'
She tried to argue but she saw it was useless. Her brother was determined to go through with it. Whimpering, she turned over on the bed, her stiff-nippled tits swaying and jiggling. She was on her knees, her face on the mattress.
'Bring your ass closer to the foot of the bed, Sis,' her brother told her.
As if she didn't have a will of her own, she awkwardly moved so that she was close to the end of the bed, her ass high, her face and shoulders resting on the bed. Her bound hands made it difficult but her brother was pleased with the position she had placed herself in.
When he switched the radio on and turned it up loud, she grew even more apprehensive. Music blared throughout the room. She knew he didn't have it on because he wanted to listen to music at a time like this. He had it on to lessen the sounds she might be making soon.
'Ron… no!'
Her hair fanned across the bedspread as she struggled feebly. Her rounded ass was raised high in the air, just the way her brother wanted it. She could see he was excited. He was squeezing his cock, as though to relieve some of the tension that was building up in it. She could see his prick throbbing. When he squeezed, a clear drop of seminal fluid leaked from the cockhead. She lay with her head to one side. She was shaking.
Suddenly her brother swung the towel in a wide arc, barely brushing her satiny smooth globes. Laura let out a gasp. She squirmed and moaned when he put his hand on her ass. Her flesh quivered to his touch. Her smooth and warm butt was trembling.
'Get ready now,' he said, teasing her some more.
She knew now what she was in for. There was no getting out of it. Her brother wasn't about to change his mind. She squirmed as he felt and fondled the cheeks of her ass. Her lush tits were pressed against the mattress, their soft flesh oozing to the sides. She let out a little whimper when his fingers tickled the soft tissue of her cunt- lips.
Then he let her have it, a stinging slap with the wet towel, right across her ass. Laura gasped, closed her eyes and buried her face in the mattress. He gave it to her then, swat after swat, one stinging blow after another, across both cheeks. Laura let out a shocked cry, sobbed and tried not to scream, as her brother laid it on her. Mercilessly he walloped her across her butt again and again, while she stifled her screams by pressing her face into the mattress. As the wet towel stung her ass over and over, her wriggling, ravaged ass twisted and squirmed. It seemed to her in her pain-racked mind that her brother was getting a little carried away, but that was to be expected. She began to think it would never end, but eventually his arm began to tire. As he dropped the wet towel to the floor, she saw through tear-dimmed eyes his hand was kneading and stroking his bone-hard pecker.
Then she saw him squeezing a lubricant out of a tube and smearing it all over his cock. Seconds later he was on the bed with her. She felt him grabbing her ass, clutching her buttocks with both hands. He pushed her knees apart, spreading her shaking thighs, opening the crack of her ass to his attack.
She sobbed and squirmed, but she couldn't escape. She groaned as his fiery cock prodded her asshole. Then she felt him push, the head of his prick poked it's way in past her sphincter muscle. He went in deeper, and then he was fucking her in the ass.
His hands reached under her and he got a hold of both her tits, squeezing them gently in each hand. Then one hand moved to her cunt.
'I'll play with your pussy, Sis,' he panted. 'I want you to come off when I do!'
Laura would never admit to him that she already got off twice while he was brutalizing her ass with that wet towel. But he was right. She moaned with delight as he fingered her excited twat, while he drove his cock back and forth in her ass. She didn't want him shooting off his load without her getting hers too.
With a lustful cry she shoved her ass back against his invading pecker, while he diddled her pussy and mauled her excited tits. Her brother panted and gasped each time he drove his cock into her bum. His chest was pressed against her back, or would have been, had it not been for her hands bound behind her. With her tied the way she was, he had to do it all, finger her pussy and tease her nipples, and still keep his mind on moving his prick in and out of her ass with a steady rhythm. But she could still do something. She could shove her ass back at him, thrust her asshole at him each time he drove his cock at her. And she could wriggle her buns like mad, rolling her hips around on his imbedded shaft. There were many things she could do to drive her brother crazy. And in her frenzy she did them all, and forgot all about the whipping he had given her ass.
With his hands clutching her by her cunt and one of her tits, he drove her wild with his cock, pulling it almost out of her ass, then cramming it all back in there, again and again and again. Babbling almost incoherently he told her how much he loved the feel of her asshole, how it felt so smooth and satiny and how it gripped him even tighter than his mother's did, when he had it up her butthole.
She was the best, her brother told her panting and groaning, the very best of everything. He fucked her asshole faster and faster, thrilled by her cries of submission, the feel of her ass pushing against his groin. Each time he plunged fully into her, her bum cheeks spread themselves, two rounded globes of soft satiny flesh rubbing against him.
Her brother was ass-fucking the hell out of her, and that thrilled her right down to her toenails. She was crying tears of pleasure, making noises of nearly unbearable joy, feeling him grinding his hips against her ass, pushing his cock into her butthole as far as he could get it. She was squealing, shrieking and babbling nonsense words, in the throes of a wildly intense orgasm, from his fingers doing outrageous things to her cunt and his cock doing even more outrageous things to her asshole.
Holding her by her cunt and one of her boobs, he fired off his load, shooting her rear passage full of his gushing juices. He was babbling like he was out of his mind, telling her how much he loved her gorgeous ass, loved ass-fucking her, and she laughed joyfully. They rolled onto their sides and lay there, trying to catch their breath, her brother's cock still in her ass.
Sometime later he withdrew his prick from her butthole and untied her. They got off the bed and with their arms about each other, they went into the bathroom and showered. While he coated her tits, cunt and ass with a
